    • A pitch break connector (10) is provided. The pitch break connector (10) has an outside (200) and inside rigid member (100). Each member (100, 200) has a first generally U-shaped channel (102, 202) defined by a spine member between first and second legs. Each member (100, 200) has a first (104, 204) and a second (106, 206) pivot end portion. A hinge (300) pivotally connects the inside (100) and outside (200) members through the pivot end portions (104, 106, 204, 206) in a generally longitudinally opposing position. In this configuration, the first and second end portions (104, 106) of the inside member (100) can be pivotally accepted into a cavity (202) defined by the generally U-shaped channel of the outside (200) member when the members (100, 200) are pivoted about the hinge (300)

    • Disclosed is an in-line skate wheel (1) that includes: (a) a braking portion (4) including a high friction surface material having a hardness from about 75 to about 95 Shore A, and a coefficient of friction from about 0.45 to about 1.5; and (b) a skating portion (5) including a low friction surface material having a hardness from about 75 to about 95 Shore A, and a coefficient of friction from about 0.1 to about 0.45. The skating portion includes a higher proportion of low friction surface material than the braking portion. The wheel delivers variable traction in response to the angle of wheel contact with the ground, without sacrificing a smooth ride or wheel durability. Utilizing the variable traction of the wheel a skater can stop safely and reliably, using known iceskating maneuvers, wherein the wheel is turned away from the skater's direction of travel.
    • 公开了一种直排轮滑轮(1),其包括:(a)制动部分(4),其包括具有约75至约95肖氏A的硬度的高摩擦表面材料,并且摩擦系数约为0.45至 约1.5; 和(b)包括具有约75至约95肖氏A的硬度和约0.1至约0.45的摩擦系数的低摩擦表面材料的滑冰部分(5)。 滑冰部分包括比制动部分更高比例的低摩擦表面材料。 响应于车轮与地面接触的角度,车轮可以提供可变的牵引力,而不会牺牲平稳的骑行或车轮的耐久性。 利用轮子的可变牵引力,溜冰者可以使用已知的溜冰操作来安全可靠地停止,其中车轮被转过来离开溜冰者的行进方向。
